“The story of how we got the equals sign” by Emma Bell, chalkdust magazine

Roots: All things being equal, by Emma Bell in chalkdust magazine

“The equals sign was invented as shorthand by Robert Recorde, a Tudor mathematician and doctor who published widely on a variety of topics. He was born in Tenby, Wales in around 1510, and died in Southwark in 1558 whilst in prison for not paying a fine.”
